Description

Technical Field

[0001] The utility model relates to the technical field of rearview mirrors, in particular to a rearview mirror component capable of independently monitoring glare. Background Art

[0002] When a vehicle is driving, the rearview mirror is an important tool for the driver to observe the situation behind the vehicle. Its performance directly affects driving safety, especially when driving at night or during bright daytime. The strong light or glare from the vehicle behind will often be reflected into the driver's eyes through the rearview mirror, causing blurred vision and increasing driving risks. In order to address this problem, a variety of exterior rearview mirrors with anti-glare function have appeared on the market.

[0003] Traditional anti-glare technology relies primarily on sensors on the interior mirror to receive information about rear light sources and adjust the transmittance of the exterior mirror's EC (Electrochromic) lens based on the received light intensity signal to reduce reflected light and prevent glare. However, this design has some obvious limitations in practical applications. For example, when the rear windshield is blocked, such as when loaded with cargo or equipped with a sunshade, the interior mirror sensor may not be able to capture rear light source information in a timely and accurate manner, rendering the exterior mirror's anti-glare function ineffective. Furthermore, in dense urban traffic, the rear vehicle may be close and at a height that may obstruct the lights of the vehicle behind. Alternatively, obstacles such as the in-car television or passengers' heads may block some light, further affecting the normal operation of the interior mirror sensor.

[0004] To solve the above problems, we have proposed a rearview mirror assembly that independently monitors glare, effectively avoiding the limitations of light source sensor detection caused by occlusion without affecting the appearance, while effectively improving the accuracy of light source detection and thus enhancing the practicality of the anti-glare rearview mirror. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a rearview mirror assembly capable of independently monitoring glare, thereby solving the above-mentioned problems.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a rearview mirror assembly for independently monitoring glare, comprising an exterior rearview mirror and an interior rearview mirror, wherein both the exterior rearview mirror and the interior rearview mirror comprise a shell and a lens, the lens being fixedly connected to the shell, the lenses of both the exterior rearview mirror and the interior rearview mirror being EC lenses, a first light source sensor being provided on the exterior rearview mirror, the first light source sensor being used to detect external light intensity, a second light source sensor being provided on the interior rearview mirror, the second light source sensor being used to detect ambient light intensity, the first light source sensor and the second light source sensor being electrically connected to signal input terminals of a controller for adjusting the transmittance of the EC lenses of the exterior rearview mirror and the interior rearview mirror respectively, and the controller adjusting the transmittance of the EC lenses of the exterior rearview mirror and the interior rearview mirror according to the light intensity difference detected by the first light source sensor and the second light source sensor.

[0007] In the above solution, the exterior rearview mirror's EC lens is equipped with a BSD module, and a first light source sensor is located on the BSD module. A BSD display area is hollowed out on the inner side of the EC lens, and an anti-glare light sensor is hollowed out next to the BSD display area. The first light source sensor detects external light intensity through the anti-glare light sensor. The BSD module serves as the vehicle's blind spot monitoring light. This arrangement allows the first light source sensor to be integrated with the BSD module, reducing the size and saving installation space. Furthermore, the EC lens's outer surface is free of additional components, which does not affect the exterior rearview mirror's appearance. Furthermore, the integration allows for a shared connector, reducing wiring harness and wiring routing complexity.

[0008] In the above solution, the first light source sensor is located within the BSD module, away from the light-emitting assembly of the BSD module. This arrangement allows the first light source sensor and the light-emitting assembly to be located in different areas. The light source of the light-emitting assembly cannot penetrate the area of ​​the first light source sensor, ensuring that the light-emitting assembly does not affect the detection effect of the first light source sensor.

[0009] In the above solution, the controller is arranged on a door module of the vehicle.

[0010] In the above solution, a connecting seat for connecting to a lens angle adjustment mechanism is provided on the middle portion of the back side of the EC lens.

[0011] In the above embodiment, the connector is a snap-on connector with several notches spaced evenly apart. Each notch is provided with a snap-on connector for securing the lens. The ends of the snaps are provided with inclined protrusions for strengthening the connection. This arrangement facilitates the connection of the lens angle adjustment mechanism and provides a more stable connection.

[0012] In this solution, the controller adjusts the EC lens's transmittance, and thus its reflectivity, by adjusting the input voltage to the EC lens. This setup allows the EC lens's reflectivity to be quickly and automatically adjusted when glare is present, reducing reflected light and preventing it from affecting the driver.

[0013] Compared with the prior art, the present invention provides a rearview mirror assembly that independently monitors glare, which has the following beneficial effects:

[0014] The present invention's independently glare-monitoring rearview mirror assembly features a first light source sensor and a second light source sensor, respectively, on the exterior and interior rearview mirrors. A controller receives the light intensities detected by the two light source sensors and compares the external light intensity detected by the first light source sensor with the ambient light intensity detected by the second light source sensor. If the external light intensity detected by the first light source sensor exceeds the ambient light intensity detected by the second light source sensor, glare is determined to be present. The controller then adjusts the voltage input to the EC lens to reduce its reflectivity, weakening the reflected light from the EC lens and thus preventing glare for the driver. The present invention's independently glare-monitoring rearview mirror assembly significantly improves the accuracy of glare detection, resolving the prior art issue where the light source sensor in the interior rearview mirror may fail to detect glare, thereby enhancing driving safety.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1-3 The rearview mirror assembly with independent glare monitoring shown includes an exterior rearview mirror 1 and an interior rearview mirror 2 .

[0021] Both the exterior rearview mirror 1 and the interior rearview mirror 2 include a housing and lenses. Both lenses are preferably EC lenses 11, which are electrically connected to a controller 3. The controller 3 adjusts the light transmittance of the EC lenses 11 by adjusting the input voltage to the EC lenses 11, thereby changing the reflectivity of the EC lenses 11. This arrangement allows the reflectivity of the EC lenses 11 to be quickly and automatically adjusted when glare is present, reducing reflected light and preventing it from affecting the driver.

[0022] The structure of the housing can be configured as required, or an existing housing can be used.

[0023] A second light source sensor 21 is provided in the rearview mirror 2. The second light source sensor 21 is used to detect the ambient light intensity in front of the vehicle. The second light source sensor 21 can be positioned as needed and can be positioned on a side surface of the housing of the rearview mirror 2. The second light source sensor 21 should be positioned in a manner that ensures that it only receives ambient light from the front of the vehicle and is not susceptible to receiving other external light sources. For example, the second light source sensor 21 can be positioned on the left or right sidewall, the lower sidewall, or the front sidewall of the housing of the rearview mirror 2.

[0024] The installation location of the controller 3 can be selected as needed. For example, the controller 3 can be set on a door module of the vehicle.

[0025] A first light source sensor 13 is provided on the exterior rearview mirror 1. The first light source sensor 13 is used to detect the external light intensity. The arrangement of the first light source sensor 13 can be selected as needed. For example, it can be arranged on the front side of the EC lens 11, or on the housing, or as Figure 2 The method shown is preferably provided on the back of the EC lens 11 and integrated into the BSD module 12 .

[0026] The exterior rearview mirror 1 has a BSD module 12 mounted on the EC lens 11. A first light source sensor 13 is mounted on the BSD module 12. A BSD display area 15 is hollowed out on the inner side of the EC lens 11. An anti-glare light receiving area 14 is hollowed out next to the BSD display area 15. The first light source sensor 13 detects external light intensity via the anti-glare light receiving area 14. The BSD module 12 functions as the vehicle's blind spot monitoring light. This arrangement allows the first light source sensor 13 to be integrated with the BSD module 12, reducing the size and conserving installation space. Furthermore, the EC lens 11 has no additional components on its outer surface, which does not affect the exterior rearview mirror's appearance. Furthermore, the integration allows for a shared connector, reducing wiring harness routing complexity.

[0027] Preferably, within the BSD module 12, the first light source sensor 13 is disposed at a location away from the light-emitting component of the BSD module 12. With this arrangement, the first light source sensor 13 and the light-emitting component are disposed in different areas, and the light source of the light-emitting component cannot penetrate into the area of ​​the first light source sensor 13, thereby ensuring that the light-emitting component does not affect the detection effect of the first light source sensor 13.

[0028] A connecting seat 4 for connecting the lens angle adjustment mechanism is also provided on the back of the EC lens 11. The structure of the connecting seat 4 can be set as needed, for example, Figure 3 The illustrated snap-on connector has several notches spaced evenly apart, each with a snap 41 for securing the connection. The ends of the snaps 41 are provided with inclined protrusions for strengthening the connection. This arrangement facilitates the connection of the lens angle adjustment mechanism and makes the connection more stable.

[0029] The present invention's independently glare-monitoring rearview mirror assembly features a first light source sensor and a second light source sensor, respectively, on the exterior and interior rearview mirrors. A controller receives the light intensities detected by the two light source sensors and compares the external light intensity detected by the first light source sensor with the ambient light intensity detected by the second light source sensor. If the external light intensity detected by the first light source sensor exceeds the ambient light intensity detected by the second light source sensor, glare is determined to be present. The controller then adjusts the voltage input to the EC lens to reduce its reflectivity, weakening the reflected light from the EC lens and thus preventing glare for the driver. The present invention's independently glare-monitoring rearview mirror assembly significantly improves the accuracy of glare detection, resolving the prior art issue where the light source sensor in the interior rearview mirror may fail to detect glare, thereby enhancing driving safety.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
